FIGS. 1-16 . Referring first toFIG. 1 ,construction equipment 10 is shown that includes machine or skid-steer loader 12 operably coupled to anattachment assembly 14.Attachment assembly 14 can be configured to drill holes in substrate such as earth, for example, utilizing an auger.Attachment assembly 14 can include an auger assembly that can include a vertically slidingmast 16 extending to a headblock structure (boom) 18 which extends to a set ofextendible Kelly bars 20. Additionally,attachment assembly 14 can include a pair ofdual side outriggers 22.Outriggers 22 can be extended during operation of the auger assembly in boring or digging operations, or they can be extended for storage of the attachment assembly when detached fromskid steer 12. - In accordance with example implementations,
distance 13 from the front of the skid steer boom to the far edge of the assembly can be less than five feet or about 4′-9″;distance 15 between the uppermost portion of the attachment and the end the Kelly bar assembly when recoiled can be less than 7 feet or about 6′-11″;distance 17 between the uppermost portion of the attachment and the supporting surface can be less than 10 feet or about 9′-11″.Distance 19 between the end of the recoiled Kelly bar assembly and the surface can be less than 3 feet. - Referring next to
FIG. 2 , in accordance with example implementations,attachment assembly 14, particularly auger assembly that includesmast 16 and Kellybar assembly 20, can be configured to rotate along an axis aligned normal to their extended axis. As shown, the auger assembly can be rotated between a horizontal position (typically used for storage or travel) and a vertical position (typically used for augering/boring). - Additionally and in accordance with example implementations,
side tilt 21 can be as much as 90 degrees, withalternating side tilt 23 being as much as 90 degrees. In accordance with example implementations,tilt 21 can be −90 degrees andtilt 23 can be +90 degrees. Anexample distance 25 for wheel support base can be 6 feet or less. Utilizing side tilt the attachment assembly can be used to provide holes that offset from perpendicular to the surface of the substrate being augered/bored. - Referring next to
FIG. 3 , themast 16 and Kellybar assembly 20 can be configured to rotate or hinge upon the axis of the boom, allowing for the transition of the Kellybar 20 in relation tomast 16. For example,angle 33 is shown at about 75 degrees, howeverangle 33 can rotate as much as 180 degrees. This hinged configuration in relation to the attachment frame can allow for the mast to be between the attachment frame and Kelly bars in one configuration (typically when actively augering/boring) and another wherein the mast and Kelly bar face the attachment frame (typically in storage or transport). - Referring next to
FIG. 4 , in one operable configuration,mast 16 and Kellybar assembly 20 can be configured for transport by aligningmast 16 and Kellybar assembly 20 in a substantially horizontal relationship in relation to the skid steer as shown in an alternative view inFIG. 5 , from a top level.

As can be seen,Kelly bar assembly 20 provides a depth up to 40′ when being utilized, while only occupying a 10′ height from elevation as shown. As is shown, the drill depth can be multiple times the height of the machine, and the machine can be small enough fit inside of buildings and dwellings in lieu of stating actual height and depth. Accordingly, distance 61 from the support surface to the base of a dig can be as much as 25 feet. Additionally, anauger width 62 can be as large as 36 inches. - Referring next to
FIG. 14 and the accompanying details ofFIG. 7 ,Kelly bar assembly 20 is shown that includes aswivel 201 coupled to astop sleeve retainer 202 which is operatively coupled to astop sleeve 203 which is operatively coupled to astop ring 204.

In another detail, awasher wedgelock 214 can be operatively engaged with abolt 215. Continuing on to the terminal end of theKelly bar assembly 20, aspring housing 216 can be operably coupled to aspring elastomer 217 which is operatively coupled to a Kelly bar inner 218 which is engaged with theauger adapter assembly 221 which can be operably engaged usingkey stock 219 andspring pin 220. In accordance with example implementations,assembly 20 can includebolts 222coupling washer 223 toplate spring 224 andplate spring spacer 225 coupled to bolts and washer wedgelocks 226 and 227. While pins, bolts, or keys may be referenced it is recognized that these coupled devices as well as friction itself may be used to affix one or more the components of the assembly. - Referring to
FIG. 15 , a more detailed view of theauger adapter 311 is shown in combination withauger 80. Referring next toFIG. 16 , a detailed view ofauger adapter 311 is shown. - In compliance with the statute, embodiments of the invention have been described in language more or less specific as to structural and methodical features. It is to be understood, however, that the entire invention is not limited to the specific features and/or embodiments shown and/or described, since the disclosed embodiments comprise forms of putting the invention into effect.

a pair of outriggers, each of the outriggers associated with a lateral edge of the attachment frame; and
an auger assembly operatively engaged with the attachment frame between outriggers.
2. The skid-steer loader attachment assembly of claim 1 wherein the attachment frame further comprises a pair of sleeves, each of the sleeves defining one of the lateral edges of the attachment frame and configured to slidably engage an outrigger.
3. The skid-steer loader attachment assembly of claim 2 further comprising hydraulic pistons operably aligned with each of the outriggers.
4. The skid-steer loader attachment assembly of claim 1 wherein the auger assembly further comprises a mast and Kelly-bar assembly.
5. The skid-steer loader attachment assembly of claim 4 wherein the mast is pivotably coupled to the attachment frame and operable to rotate the mast and Kelly-bar assembly between a horizontal position to a vertical position.
6. The skid-steer loader attachment assembly of claim 4 wherein the mast is hinged to the attachment frame and operable to swing between a first position wherein the Kelly-bar assembly and mast face the attachment frame, and a second position wherein the mast is between the Kelly-bar assembly and the attachment frame.
7. A method for performing earth augering using a skid-steer, the method comprising:
extending dual outriggers from a boom assembly of a skid-steer to engage substrate; and
extending an earth auger into the substrate from an auger assembly that is operably engaged between the dual outriggers.
8. The method of claim 7 wherein the extending the dual outriggers comprises operatively engaging a hydraulic system to slide outrigger posts within sleeves of an attachment frame.
9. The method of claim 8 further comprising extending each of the dual outriggers separately.
10. The method of claim 9 further comprising, prior to extending the earth auger into the substrate, rotating an earth auger assembly from a horizontal position to a vertical position.
11. The method of claim 10 further comprising swinging the earth auger assembly upon a hinge to align a mast of the earth auger assembly between Kelly-bars of the earth auger assembly and the boom assembly.
12. The method of claim 7 further comprising extending the earth auger at an angle other than perpendicular to the substrate surface.
13. A skid-steer loader and attachment assembly configured to perform earth augering, the loader and attachment assembly comprising:
a skid-steer loader equipped with a boom assembly extending from the skid-steer to an attachment end of the boom assembly;
an attachment frame coupled to the boom assembly of the skid-steer loader, the attachment frame extending horizontally between lateral edges;
a pair of outriggers, each of the outriggers associated with a lateral edge of the attachment frame; and
an auger assembly operatively engaged with the attachment frame between outriggers.
14. A boring assembly coupling assembly, the assembly comprising:
a boring member configured to be rotated when boring/augering, the boring member terminating in a first flange; and
an auger adapter configured to couple with an auger bit, the auger adapter comprising a second flange configured to compliment and reversibly couple with the first flange.
15. The boring assembly coupling assembly of claim 14 wherein the auger adapter further comprises a complimentary shaft configured to couple with the auger bit.
